Beschreibung
Zusammenfassung:	According to the present invention, provided is a proximity sensor comprising: a light emitting unit emitting a first light having a specific wavelength band; a light receiving unit receiving the first light and a second light having a wavelength band different from the first light wavelength band; a control unit recognizing an adjacent object based on the first light reflected by the adjacent object. The control unit changes a light receiving range of the light receiving unit based on the second light. According to the present invention, a recognition error can be resolved caused by external optical interference. 본 발명은, 특정 파장 대역의 제1 광을 발광하는 발광부, 상기 제1 광 및 상기 제1 광과 다른 파장 대역의 제2 광을 수광하는 수광부 및 근접 물체에 의해 반사된 상기 제1 광을 근거로 상기 근접 물체를 인식하는 제어부를 포함하되, 상기 제어부는, 상기 제2 광을 근거로 상기 수광부의 수광 범위를 변경하는 것을 특징으로 하는 근접 센서를 제공한다.
